8/5:Oakland Raiders defensive end Khalil Mack has yet to report to Raiders training camp this summer, continuing his holdout for a new contract. Mack has 10 or more sacks in each of the last three seasons, bringing some upside to what is a low-cost defense to draft. According to Ian Rapoport, NFL Network, there have been no talks with Mack dating back to February, which should be a concerning note. Mack offers a solid floor along with solid upside in an IDP league while bolstering the numbers of the Raiders defense. As training camp continues, we will continue to get more news regarding what is a very unclear contract situation.--Tom Vecchio - RotoBallerSource: Ian Rapoport, NFL Network
